【発明の名称】同一方向に伝播する、並びに反対方向に伝播する偏光誤差の抑制を変調した光ファイバジャイロスコープ
Document Type and Number:
Japanese Patent JP2002532705
Kind Code:
A
Abstract:
A fiber optic gyroscope having polarization error-correcting modulation. Polarization errors originate from the interference of primary waves and secondary cross-coupled waves. Although these error signals are very difficult to remove modulation signals may be applied to the integrated optics chip that minimize the total error over a period of time. By providing distinct but inter-related modulation signals to opposing inputs of the sensing coil, the various polarization errors can be averaged to zero over the period of the modulation signals.
